This creamy Tomato Basil Soup is loaded with hidden vegetables and is restaurant-quality DELICIOUS! You can make it on the stove, slow cooker or in the Instant Pot. 

I love making soup for dinner because it’s so easy to make (and sneak those vegetables in to) and it’s easy to come up with things to serve with it, like an Italian Grilled Cheese Sandwich!  Some of my other favorite soup recipes include: Broccoli Cheese Soup, Creamy Chicken and Wild Rice Soup, and Spicy Chicken Soup.

I have been in LOVE with this soup Tomato Basil Soup recipe for nearly a decade! I have a few different recipes for tomato soup on my site but this one is probably my favorite, and I love how it has veggies hidden inside it! It tastes great and is a little more nutritious than a typical creamy tomato soup. It tastes even better the next day if you want to make it in advance or enjoy meal prep leftovers in your fridge.

How to Make Tomato Basil Soup:

  • Sauté the vegetables: Add the carrots, onion and celery to a pot with a little bit of oil and sauté them for a few minutes.
  • Add: diced tomatoes, tomato paste, chicken broth, oregano, and basil. Bring to boil and cook for several minutes, until the vegetables are tender.

  • Blend. Use an immersion blender or regular blender (you may need to do this in batches, depending on how big your blender is) and purée the soup until smooth. Return it to the soup pot.
  • Make the roux: In a separate pot, add butter and melt on medium heat. Stir in the flour and whisk together constantly for about 10 minutes or until the roux is a nice golden brown color.
  • Add the roux: Stir a big ladle full of soup into the roux-it will start to form a thick paste.  Slowly add another 2-3 cups of warm soup to the roux, whisking it until smooth. Add the mixture to the soup pot and stir well to combine.

  • Stir in parmesan cheese, half and half (or milk), and salt and pepper. Add additional oregano and fresh basil as desired, to taste. Stir well. Cook for a few more minutes until warmed through.

For Slow Cooker Tomato Soup:

  1. Add to slow cooker: diced tomatoes, carrots, onions, celery, tomato paste, chicken broth, oregano, and basil.
  2. Cover and cook on low for 5-6 hours until flavors are blended and vegetables are soft.
  3. Make the roux: About 30 minutes before the soup is ready, prepare a roux. Melt the butter over medium low heat in a skillet and add the flour. Whisk together constantly for about 10 minutes or until the roux is a nice golden brown color.
  4. Thicken soup.  Slowly add 1 cup of the soup from the slow cooker to the roux–it will start to form a thick paste.  Slowly add another 3 cups of warm soup to the roux. Whisk together until smooth. Add the roux mixture to the slow cooker and stir to combine.
  5. Blend: Pour soup into blender (you may need to do this in batches, depending on how big your blender is) Purée until smooth. Return to the slow cooker.
  6. Stir in the Parmesan cheese, half and half (or milk), and salt and pepper. Add additional oregano and basil if needed, to taste. Stir well.
  7. Finish cooking. Cover and cook on low for another 20-30 minutes or until warm.

Storing and Freezing Instructions:

  1. Excellent soup, very satisfying for a cold winter day. Good amount of healthy veggies. I made no substitutions can’t wait for a piece of crusty French bread and butter to go along with a nice bowl of warm soup! I’ll make it again.

  2. This soup was very good. I don’t like the texture or taste of carrots in tomato soup so I’ll leave those out next time but this is a great tomato soup. I like the flavor of fire roasted tomatoes so I might try those with this recipe. I am loving this site and enjoying new dinner options!

  3. Made your beautiful from scratch tomato basil soup. Im so inspired by great cooks on Pinterest. Im a single 71 year young woman. Still cooking after all these years. Always share the end product, and always let people know about the new way to research and cook.

  4. 5 stars
